I Specification of Letters Patent.

Application filed April 24, 1908.

Patented Nov. 5, 1912. Serial No. 423,974.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in CementingMachines, of which the following description, in connection with the accompanying drawings,

is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for applying liquid materiaL-such as cement, to shoes or other stock and particularly to machines for applying cement to the channeled of cement in relation to the rate at which the work is advanced for receiving its coating, and still anotherobject is to provide improved means for spreading the cement on the work.

A very important feature of this invention consists in a machine arranged to pro vide a continuous flow of cement while the work is in place with means for automatically shutting oif the delivery of cement when the work is withdrawn from receiving position. Preferably, also, means is provided for starting the flow of the cement when the work is moved toward or into its receiving-position, and insuring the con tinued flow until the work is withdrawn. By stopping the delivery of cement automatically when the shoe is withdrawn, waste of cement is avoided and also objectionable overloading of the cement-applying brush which is likely to occur when the operator controls a alve by a foot treadle and often fails to shut it oil as soon as a shoeis finished. By also starting the cement automatically the use of the usual treadle can be entirely avoided and economy in the use of cement effected because cement will only be delivered while the shoe is in position to receive it.

Another feature of this invention that is of great importance consists in cement ap plying means. constructed and arranged to deliver cement to the work in proportion to the advance of the work. This feature is of especial importance in such work as channel cementing in which the rate at which the work can conveniently be fed ivaries at different points. It is possible, and in practice desirable, to advance the shoe very rapidly'while the relatively straight sides are being coated but when the toe is reached and the shoe must be turned the advance is necessarily slower than it may be at the sides. .It is however not necessary to supply at the toe a correspondingly greater quantity or coating of cement. By this invention approximately the same quantity of coating of cement may be applied during the slow advance at the too as during the more rapid feed at the sides.

A further important ch aracterist-ic of this invention is found in the combination with means for supplying cement in proportion to the advance of the work, of means for spreading the cement which is operated independently of the rate of feed of the work. This enables the operator by varying the rate of feed to obtain a more thorough spreading of the cement at the parts of the work which for any reason require especial care, such, for example, as the crumpled lip of the soleat the toe of the shoe.

A "more specific feature of the invention is found in a construction in which a brush is arranged to be rotated by contact with the work and to deliver cement by this movement while ithas a 'movement in a different direction, as, for example, an axial reciprocatory movement to spread the cement. In a channel cementing machine the axial movement transversely of the channel lip is particularly advantageous in working cement into: the folds of the inwardly turned and crumpled portion of the lip at the toe.

A further feature of thelinvention 0011-,

cementing the channeled portions of a shoe sole which comprise the feather and the overturned or partially overturned channel flap. In this operation it is important to get cement into the angle at the base of the flap and the movement of the brush forth and back transversely of the feather and flap effects this placing of the cement in a superior manner in addition to spreading it properly over the face of the flap and feather.

These and other features of the invention, including numerous details of construction and combinations of parts, will be more fully explained in connection with the draw ings and will then be pointed out in the claims.

Figure 1 is a side view of a machine embodying the invention in one of the best forms now known to me; Fig. 2 is a section of Fig. 1 on line 2-2. Fig. 3 is a section of Fig. 1 on line 3 3.

The frame 2 of the machine has bearings for a driving shaft 4 provided with a belt pulley as shown in Fig. 1 and the head of the frame supports or is shaped to form a reservoir 6 for holding a quantity of cement. The bottom of the reservoir preferably slants as indicated toward the outlet at the front of the machine. About this outlet the reservoir is formed to receive the conductor 10, which is removably attached to the reservoir and may be differently formed according to the cement applying means to be employed. As shown in Fig. 1, the conductor terminates in the vertically bored portion open at its lower end and provided with a seat for the valve 12 which is normally pressed downwardly by the spring 13. The casting of which the conductor is a part extends downwardly and also rearwardly and forms a support for the brush carrier 14. This carrier is mounted to have movement both horizontally and vertically, being connected to the casting by a pin and slot at 15 and forked at 16 to embrace and be guided by a depending portion of the casting. This arrangement permits the brush to be lifted by the engagement of the worktherewith. The brush carrier is shaped to form a cement box 20 located directly above the brush and having an inclined floor terminating in an outlet at 22. The cement box also has a post 24 which is located relatively to the valve 12 so that when the brush is lifted by the work the valve will be opened to permit discharge of the cement from the conductor into the eeto turn upon an axle 27 by its surface ongaging with the work. When no work is in position the brush stands idle, the cement being shut off by the valve 12, and when. the shoe is advanced in contact with the brush the latter turns merely with the speed of the work. The brush is provided with fingers 28, shown as blades, which may be supported by or formed upon a flange 30 secured to the hub of the brush. These fingers extend approximately to the periphery of the brush and are adapted to engage the work. They facilitate the turning of the brush by the work and they also constitute a substantially rigid element against which the shoe may be pressed upwardly for raising the brush and opening the valve. The fingers are shown as extending only partially across the width of the brush and are located to engage the feather of the sole. They may serve as a lateral abutment for the base of the channel flap and therefore as guiding devices for determining the lateral position of the shoe with relation to the brush. When the fingers are used for this purpose they will terminate at their front or right hand ends, in Fig. 1, in such a position with relation to the width of the brush that they will prevent the brush from extending over the edge of the channel flap into such a position that cement might get upon the face of the shoe sole. It should be noted that these fingers engage the sole successively as said sole is advanced and that this successive engagement tends to cause a vibrating movement of the carrier and hence of the valve, the advantage of such movement being due to the viscosity of the cement which renders its normal flow somewhat sluggish. An edge guide 32 is shown in Fig. 1 which may be used either alone or in conjunction with the fingers 28 to determine the lateral position of the work with relation to the brush.

As above mentioned, the brush carrier 14 is movable horizontally or endwise. Between the rear end of the carrier and the shaft t there is arranged a rod 84- having one end in an eccentrically located socket 35 of a disk that is rotated by the shaft. The. other end of the rod 34 is seated in a socket plate 37 adjustably mounted on the rear end of the brush carrier, the sockets being so located that the inclination of the rod is alternately increased and decreased as the shaft turns. By this arrangement the brush carrier is moved forwardly by the rod at each rotation of the shaft 4 and the length of the reciprocating movements may be varied by adjusting the plate 87. A spring 36 reversely moves the carrier, thus eifectin g with the rod a reciprocation of the brush lengthwise of its axis and transversely of the channeled portions of the shoe sole. By this means the cement, which is supplied in proportion to the upward pressure of the work against the brush, is thoroughly worked into the angle between the channel flap and the feather of the sole.

Certain features which are common to this application and to applicants co-pending application, Ser. No. 428,975, have been claimed in said co-pending application.
